WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent No. 394,553, dated December 18, 1888.

Application filed May 14, 1888. Serial No. 273,856. (No model.)

To all whom it DMLZ/ concern.-

Be it known that I, FREDERICK A. BERNARD. a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have invented a new and useful Improvement in \Vindow-Blinds, of which the following is a specification.

My invention pertains to that class of window-blinds in which the blinds are mounted between the jambs of the window and are adapted to slide up and down like Windowsash; and it relates more particularly to the mounting and arrangement of the blinds and the manner of securing them in the windowframe.

My invention is more especially adapted to blinds having stationary panels with rolling slat shutters hinged thereto, as shown in the drawings.

One object of my invention is to provide means whereby the blinds can be slid up and down when open and when closed, and thus be arranged to admit a large amount of light when it is so desired, and whereby the blinds 2 5 can be so arranged that the light admitted can be distributed as desired.

A further object is to adapt the mountings of my improvement so that the blinds can be conveniently inserted in any window-frame 3 without disfiguring the same.

The accompanying drawings illustrate my invention.

Figure l is an elevation of the inside of a window-frame provided with my invention,

the shutters being closed. Fig. 2 is a view of the same, showing the shutters open, the lower shutterbein g partially raised. Fig. 3 is a crosssection 011 line no .r, Fig. 1. Fig. 4 is a crosssection on line y '1], Fig. 2. Fig. 5 is an isometrical view of the upper end of the jamb F.

Fig. 6 is a perspective view of one side of the frame, the molding H being removed to one side, and one of the blinds being removed to expose the stop G, which is partially removed,

and the groove 0, into which it fits.

A and Bare the frames of the two verticallysliding blinds, C C are the hinged shutters hinged to the frames of the blinds, and D D are the panels of the blinds.

The blinds are secured in the window-frame by means of the longitudinally-grooved win- (low-stops or blind-jambs E F, the removable stop G, and moldings H H, as hereinafter fully set forth.

The jamb E is provided on one side with the longitudinal groove 1, near the inner edge thereof, and longitudinal rabbet J at the outer edge thereof, in which one side of the blinds slides up and down. Between the rabbet and the groove there is aparting-stop, N, equal to or greater in width than the thickness of the shutters. The other side of the jamb E is provided with the longitudinal groove K near the inner edge thereof and longitudinal rabbet L near the outer edge, in which the balanceweights M hang. The molding II is secured to the outer edge of the jamb E, and its edges project on each side of the jamb across the rabbets J and L and transform the rabbets into grooves, in which the weight and the edge of one of the blinds slide up and down.

The jamb E, together with the molding H, thus forms a window-stop grooved on one side to form with the window-casing a weight-box, and adapted on the other side to furnish a bearing for the vertically-sliding windowblinds and hold them at such a distance apart as to allow them to slide past each other when the shutters are folded open.

The jamb F is provided on one side with a longitudinal rib, S, along the inner edge thereof and a longitudinal mid-groove, 0, midway between the rib S and the outer edge of the jainb.

The removable parting-stop G is fitted tightly in the mid-groove O and is equal to the stop N in width. \Vhen the stop G and molding H are in place on the jamb F, as shown in Figs. 3 and l, they and the rib S form the walls of the grooves in which the blinds may slide up and down. The other side of the jamb F is provided with a longitudinal groove, K, near the inner edge thereof and a longitudinal rabbet, L, along the outer edge corresponding to the groove K and rabbet L in the jamb E. The jamb F, together with the stop G and molding II, thus forms a window-stop grooved on one side to form with the window-casing a weight-box, and adapted on the other side to furnish a bearing for the vertically-sliding window-blinds.

The two stops G and N hold the blinds apart, so that when the upper shutters are I swung back upon the panels D D they will not be in the path of the lower blinds. This allows the lower blind to be raised when the upper blinds are open. Figs. 2 and 4111113 trate this feature of my invention.

The blinds are hung with sash-cords P and weights M, in substantially the same manner as window-sash.

My improved blinds may be secured to any window without injury. The jambs E and F, the head-piece Q, and the sill-piece R form a frame to receive and hold the blinds in the window-frame.

By removing the molding H the lower blind is released, so that it may be removed from the frame. In order to release the upper blind, the stop G is withdrawn from the groove 0.

I am aware of .the construction shown in United States Letters Patent issued to WValter A. Holbrook December 7, 1886, No. 353,858, and I do not claim as my invention a windowstop grooved on one side to form with the window-casing a weight-box, and grooved or otherwise adapted on the opposite side to furnish a bearing for a vertically -sliding window-blind.

Now, having described my invention, what nal rabbet at the outer edge, the opposite.

jamb being provided on one side with a longitudinal rib along the inner edge thereof and a longitudinal mid-groove midway between the rib and the other edge, and pro-- vided on the'other side with a longitudinal groove near the inner edge thereof and a longitudinal rabbet along the outer edge, the parting-stop fitted in the longitudinal midgroove, the moldings secured to the outer edge of the jambs, their edges projecting on each side of the jamb, and the sash'cords and weights.

FREDERICK A. BERNARD.
